IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 114,493, dated May 2,1871.

To all whom it may concern:

Be it known that I, BENJAMIN G. TURNER, of Fremont, in the county ofDodge and State of Nebraska, have invented certain new and usefulImprovements in Harvesters and I do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being had to the accompanying drawing, making apart of this specification, in which- Figure l of Sheet 1 is a planview. Fig. 2 of Sheet 2 is a side elevation. Fig. 3 isa sectional viewin detail of spring device for throwing machine in and out of gear. Fig.4 is a sectional view in detail of lever, showing its arrangement withpin of sickle-bar. Fig. 5 is an enlarged View of spring device.

Like letters in the different figures of the drawing indicate likeparts.

My invention relates to a combination and arrangement of devices, aswill be hereinafter fully explained.

A is theframe of the harvester; B B, the wheels; 0, the tongue; D, thedrivers seat; E, the sickle-bar, andFthe reel.

The sickle-bar consists of knives or cutters, arranged and attached, inthe usual manner, to a bar having its bearing in the bed of plate a,formed by a plate, I), being attached to the back part thereof, guides 0being secured to and across plate b at intervals, and made to lap overthe bar, so as to hold it in place, thus preventing an up-and-downvibration of it,

the knives.

The finger-bars are arranged and attached as ordinarily to the underside of the bedplate a.

The sickle-bar is supported by two plates, at

one near each end. These plates are riveted to the under side of thebed-plate, and the whole strengthened by a brace, c, consisting of aplate attached centrally to the front beam of the frame, the plate beingdepressed downwardly, so as to form a shoulder for it to come againstthe side of the beam and let in the upper edge, as well as on the sidethereof, the said plate being so made as to have an arm, f, extend outon either side and embrace the G is a lever, having its fulcrum attachedto the under side of the plate part of brace c, and connecting at oneend with a pin, h, projecting down centrally from the sickle-bar througha slot in the bed-plate, and at the other to an arm, 'i, connecting withthe crank of shaft H. The relative positions of each will be seenclearly in. Figs. 1 and 4. This lever G, in order to connect it properlywith the arm 2', is extended through a slot in the front beam, andthence through a slot in the metallic box J, attached to the inner sideof the beam, the latter-named slot afiording aproper bearing for thelever to work in, the slot in the bed-plate being made so as togiveplayenough for the pin h to work in when operating the sickle-bar.

Suitable bearings are made in the front and back beams, and fasteningsprovided to receive and hold the ends of the crank-shaft H properlytherein.

The end of the shaft next to the back beam has a beveled gear-wheel, k,arranged and attached thereon so as to be movable, the object of whichwill be hereinafter described, the said gear-wheel k meshing withanother and larger beveled gear-wheel, an, attached to a short shaft,which has its bearing in the cross-beam K, a proper fastening beingprovided to secure it therein. On the opposite end of said shaft is apinion, L, into which meshes the spur-gear wheel 0, which is attachedrigidly to the shaft of the drivingwheel B, and which latter wheel, onthe machine being drawn forward, operates the sickle-bar through thegearing just described.

The arrangement of the lever G, by which the power is imparted to thecenter of the sickle-bar instead of at the end, as in most ofharvesters, enables it to be operated more easily and with less power.

The crank-shaft His made to extend through and out from the rear beamsufficiently to re ceive the double-flanged wheel or pulley M on itsend, the said wheel or pulley connecting, by a band or chain, with asmaller one, N, attached to a rod, 0, which latter extends through andhas its bearings in the projecting ends of the front and back beams, andalso in a groove made in the side of the end crossbeam, so as to havethe rod come flush with .oted to the ends of the frame.

the surface thereof, and thus admit of the stand ard P, supporting thereel, to be properly pivoted to the side of the end beam below the rod,without interfering with its operation, and the standard, by its beingacross. the rod, will, at the same time, keep it from springing out.

The rod 0 extends out from the front beamas far as the inner edge of thebed-plate, and has a roller, Q, attached rigidly to it, the rolleroccupying the space between the front beam and bed-plate a, and turningwith the rod when it turns.

At the opposite end is another roller, Q, but which turns on a rodpermanently fastened in the side of the front beam.

To these rollers will be attached, in prac- .tice, an endless carrier orapron, (not shown in the drawing,) the object of which will be to carryoff the straw, the carrier being operated by the rod 0, receiving itsmotion from the gearing through the double-flanged wheels or pulleys M Nand band or chain connecting them together in the manner aboveexplained.

The reel issupported by standards P P, piv; The standards are provided,on their under edges, with a suitable number of notches. Supports S Sare placed under them, and suitably hinged to the lower edges of theends of the frame, by which the standards are made to adjust and holdthe reel at any position desired, by the ends of the supports beinginserted in the proper notch of the standards.

The reel is operated by a double-flanged wheel or pulley, V, on the endof the shaft thereof, connecting, by a band or chain, with .a largerone, V, on the end of the shaft of the driving wheel B, the revolutionof both wheels, when the machine is put in motion, operating the reeland the sickle-bar at the same time, as well as the endless carrier.

The tongue is hinged in any suitable man- .ner to the side of therearbeam, and is provided, as ordinarily, with a guide or tiller wheel, Z,which is so attached to the front end as to have a swivel motion, theguide or tiller Z, by which the wheel is operatcd, be-

.ing arranged in a position convenient to the feet of the driver, whoseseat is supported by a spring attached to the topof the tongue.

The segment of the tiller or guide is provided with teeth on its outeredge, and footrests' a a on each end, on which the driver puts hisfeetwhen operating the tiller.

The arm of the segment is made in two pieces I and hinged together nearthe part attached to the post of the wheel, and has a flat spring, 0, soarranged and attached to the under side across the joint of the hinge asto keep the tiller or guide slightly elevated to an inclined position,so' that when the driver desires to hold the wheel in a fixed position,he, by placing his feet on the foot-rests n'jt and pushing .the tillerdown, causes the teeth of the segment thereof to fasten onto catch 1) onthe upright rack T attached to the tongue near by,

thus holding the tiller, and preventing the wheel from turning so longas the driver keeps his feet on the foot-rests; but the moment heremoves his feet the spring releases the tiller by throwing it up to itsoriginal position.

Secured to the center of the rear beam by a staple,hinge, or othersuitable device is arod, T, the end of which is pivoted to a short leversuitably arranged and projectingforward from the inner side of the rearbeam. This rod T is for the purpose of raising and low ering themachine, either while in motion or not,'as occasion may require, and isheld by the driver placing it in the teeth of the rack T withoutremoving from his seat.

The machine is thrown in. and out of gear by a spring device and lever,arranged to connect with a rod and crank within convenient range of thedriver, the spring device consisting of a slide, q, arranged toencompass the shaft and connect with the beveled gear 70, a spring, (1,being interposed between the slide and gear to give the latter ayielding connection with gear m, so that any unevenness of bearingcaused by the shifting of gear It will be compensated bythe spring, apart of the slide being so constructed as to fit and work in a groove ofithecasting a, which casting is let down in the edge of the rear beam,and through which passes the end of the crankshaft H, this end of theshaft having its bearing therein, the said slide being held in thegroove by a plate placed across it and fastened down to the casting byset-screws o '0,

.the casting having projecting arms, by which it is'fastened to the edgeof the beam by the screws :0 w. Pivot-ed to the slide is alever, a,which has its fulcrum at 11 This lever connects by a pivot with the endof rod 0 which latter extends back and connects by a pivot with thecrank-lever d the latter lever hav ing its fulcrum at the lower end ofthe plate 0 which plate is attached to the 'side of the tongue, and hasa slight projection at its upper end, in which are two notches, h It.Thus, to throw the machine out of gear, the driver pushes the cranklever 01 forward, which, by its connections, just described, with thelever to of the slide q, causes the latter to move the beveled-gearwheel h back, hence releasing it from the beveled-gear wheel m, thecrank-lever being held by placing it in the forward notch of plate 0".

To throw the machine in gear the cranklever is, of course, pulled backby placing the gear-wheel m back where it was before, thecrank-lever,'in that case, being held in the notch nearest to thedriver.

Having thus fully described my invention, what I claim therein as new,and desire to secure by Letters Patent, is-

1. The tiller-guide Z,consisting of a segment with teeth, and foot-restsa a, and an arm made with a hinge-joint near the post of the tiller, andspring 0, arranged with the joint, as described, in combination with acatch, 1), and

drivers seat J, all constructed and attached to the front end of thetongue, as shown and described,

2. The spring device consisting of slide and spring, plate and castingu, and lever a, all arranged to connect with the beveled-gear wheel k,as described, for throwing the machine in and out of gear, incombination with the rod 0 and operating cranklever d, and
